They have a floating canvas hair panel but I'm pretty sure they also use some fusing. I own a number of suits from them and am very happy with them, yet their house style is evidently quite different from the "typical SF style" (if that exists). And yes, they are very nice people.Welsh tapestry tweed is (or was) not unusual in women's clothing (though the above picture is the only piece of menswear made of it that I've ever seen).
